CustomDataStorageWrapper

Library providing diamond storage access and the read/write primitives used by the custom data facet to persist arbitrary key/value entries on a security token.

Uses the ERC-2535 diamond storage pattern to isolate state under STORAGE_LOCATION_CUSTOM_DATA, preventing slot collisions with other facets. All entry points are internal so that callers (the CustomData facet) inline the logic rather than paying external-call overhead. Write semantics are full overwrite: each setCustomData call replaces the entire array stored under the key — there is no append or partial update.
